As you can already tell, I am a Ubuntu newbie...trying to make the big switch from Windows to Linux. I installed Ubuntu 13.04 on a partition aside from Windows. I was waiting for a prompt to ask me which OS to choose from but when I started my computer, Ubuntu loaded up automatically. I would like to have the option of choosing the loaders on Windows (white font, black background) and not the Ubuntu one (white font, purple background).

Open Dash (the ubuntu icon at the top of the bar on the left), search for "Terminal" and open it. Type in sudo update-grub there will be a prompt asking for password, just enter your user's password. After you reboot there will be a list of available operating systems, Ubuntu at the top, Windows at the bottom.

For more information about update-grub or any other command run in terminal man <command> where command==any package like update-grub or anything other program.
